ProviderSettings class not found it says Cannot resolve symbol ProviderSettings

Question

I am new to spring boot space. I am following a tutorial learning to create OAuth authentication server.

While configuring the AuthorizationServerConfig.java the instructor imports 'ProviderSettings' class from package 'org.springframework.security.oauth2.server.authrization.config'

However, I don't have that class available from that particular package.

Am I missing any dependencies? Or is the Class now not available?

Reference 1: Point of error. Cannot resolve symbol ProviderSettings

@Bean
    public ProviderSettings providerSettings(){
        return ProviderSettings.builder()
                .issuer("http://auth-server:9000")
                .build();
    }

I tried to find the correct import for the required class i.e. 'ProviderSettings'
Cross checked dependencies.

Answer 1

You won't believe me but I just solved this issue some minutes ago. Looks like the guide was using an outdated version of spring-security-oauth2-authorization-server and they renamed

ProviderSettings to AuthorizationServerSettings

https://github.com/spring-projects/spring-authorization-server/issues/864

https://github.com/spring-projects/spring-authorization-server/issues/681

https://github.com/spring-projects/spring-authorization-server/issues/986

They should add these changes to the docs or make it more clear IMO

Thank you for the guidance. I replaced ProviderSettings with AuthorizationServerSettings and it worked like a charm. Yup, they should have mentioned it. – Imbibe

Isn't standard to mark these old classes as deprecated rather than just quietly renaming them? – Habile

Answer 2

I guess you refer to this guy: https://youtu.be/zvR-Oif_nxg?t=32043 .

Actually he is not very clear in what he is doing, adding boilerplate code.

Anyway you can use the reference guide from Spring, where it is showing a working example for Authorization Server: https://docs.spring.io/spring-authorization-server/reference/getting-started.html#defining-required-components

@Bean
public AuthorizationServerSettings authorizationServerSettings() {
    return AuthorizationServerSettings
            .builder()
            .issuer("http://auth-server:9000")
            .build();
}
